ABSTRACT

PROCESS IN WHICH POLYESTER FIBER OR FABRIC IS TREATED WITH AQUEOUS SOLUTION CONTAINING TETRAKIS (HYDROXYMETHYK)PHOSPHONIUM HALIDE, TRIAZINES AND CARBAMIC ACID DERIVATIVES, DRIED, AND THEN CURED TO PRODUCE A POLYMERIC COATING ON THE POLYESTER SURFACE. THE POLYMERIC COATING IS DURABLE TO SEVERE WASHING AND REPEATED DRY CLEANINGS AND RENDERS THE POLYESTER SUBSTANTIALLY FLAME RETARDANT.
